Increased hearing sensitivity is called a feeling of discomfort in the ears, which provoked loud and annoying sounds of the outside world.Many people experience negative emotions only at very loud sounds, but there are those who are trying to avoid even the less intense noise.Every man there is a certain cause of hypersensitivity to sound, the most serious risk factors are: autism, meningitis, migraine and neurological diseases.
painful perception of sounds is called hyperacusis - a condition in which even the faint sounds are perceived overly intense.In severe cases, hyperacusis very painfully tolerated sick man.It all starts to irritate appear pronounced neurotic reactions that hamper to perceive the world around us and perform the usual current work.
If you are sensitive to the sounds of the human voice can irritate the baby, the horn of the car, running a vacuum cleaner, the sound of the door closing, the clatter of dishes and much more.These sounds are typically not only causes
emergence of increased auditory sensitivity
in the human nervous system are strong enough compensatory mechanisms.Simply put, if there are damage to the outer, middle or inner ear, the auditory system is trying to normalize a reduced amount of information that goes to the central regions, with the help of the enhancement in the auditory pathways.Sounds that should normally be transferred, become unbearable and often cause pain in the ears and a feeling of discomfort.
If you are sensitive to the sounds of maintaining a normal life becomes impossible.Many people as a result, forced to abandon the profession of musician, educator or teacher, as well as to limit contact with other people.Increased hearing sensitivity in itself is not a disease.This is - a loss of balance between these processes auditory pathways as strengthening and braking.This phenomenon causes the migration of auditory processes, resulting in a lowering of the threshold excitation.
should understand how often manifested heightened auditory sensitivity.According to research carried out is known that 40% of all cases of excessive sensitivity of hearing acts in parallel with the ear noise, or hearing loss.However, in some cases, the pathology can occur on its own, now like syndrome is diagnosed in 15% of middle-aged people.
sound reasons for increasing the sensitivity
Hyperacusia often occurs as a result of disruption of the acoustic analyzer.Often this condition is observed in the acute stage of pathological processes such as meningitis, head injury, encephalitis and cerebrovascular problems.When hyperacusis develops in childhood, it gives a very great suffering child.These children are so sensitive sleep, wake up that even a slight rustle.Over time, they begin to form an intolerance of certain sounds, which can cause headaches, dizziness or nausea.
Children hyperacusis may be partial or complete.In the first case there is irritability for a certain interval or a number of strong sound volume.At full hyperacusis same child can not tolerate just too loud.Often this condition is temporary and occurs only as a result of the influence of a certain tone sounds.Hyperacusis may cause sounds any key, and the painful perception can be either unilateral or bilateral.
CAUSE increased sensitivity to sounds can also be covered in lesions of the facial nerve, or ear inflammatory diseases.Often this state provokes paralysis stapedius muscle, which develops as a result of the defeat of the facial nerve.There are cases where increased sound sensitivity acts culminating in an attack of Meniere's disease.Chances hyperacusis progression in the development of pathological processes in the brain, mainly in the middle cerebral tumor formation area and the thalamus.In such cases, the symptoms of hypersensitivity to sounds accompanied by general hyperpathia and hyperesthesia on the side that is opposite of the pathological process.
Treatment of hyperacusis
In diseases neurological urgent way address the underlying cause of the disease with the help of sedatives and relaxation treatments.If the cause of sound intolerance lies in pathological processes which are developing rapidly in the body, it is advisable to conduct physical therapy effects on the area of the middle and outer ear.
With the purpose of treatment using the procedure flyuktuorizatsii at which the sinusoidal current of low voltage and low power, which randomly change.Such manipulations have resolving, anti-inflammatory and analgesic effects, and fluctuating currents symmetrically reduce swelling.
